Hi Hemant,

I removed the commit 14/18 from set, but it impacts other patches, I can
fix the build but can't verify the functionality, probably better if you
send a new version without patch 14/18.

Btw, while resolving conflict I recognized that patch 15/18 renames
'fman_offline_internal' -> 'fman_offline', and next patch (16/18),
renames it back to 'fman_offline_internal', this creates lots of noise
in both patches, can this be prevented, I will comment on the patch?
